These are the standard criteria in Europe for data storage. The FAIR criteria will make sure that data are managed in such a way as to benefit scientific research as a whole. Make sure your data will be stored in a repository which complies with FAIR. Examples of repositories that comply with FAIR: re3data.org, and for Switzerland in particular: DCLM long-term preservation

Costs of storage

Depending on the size of the datasets and the period of storage, repositories may charge you a fee. Make sure you include these in your planning. The SNF will reimburse storage costs for funded projects.
